Bonsall FAQ
Do I need a grading permit in San Diego County?
Yes, if your project involves moving more than 200 cubic yards of material or if cuts or fills exceed 8 feet in vertical height. Smaller projects may still need permits depending on slope and location.
Can I direct drainage onto my neighbor's property?
No. Drainage must be properly designed to not increase runoff onto neighboring properties. Altering natural drainage patterns that cause damage creates civil liability.
